Title: A history from the bottom of the sea: Fish, Microfossils, Marine Ecosystems, and Global Change
Short Abstract: Ray-finned fishes are the most diverse group of vertebrates on the planet today, and are ubiquitous in marine ecosystems. However, this wasn't always the case. In this talk, I will discuss the evolutionary and ecological history of fish and sharks, and their evolving role in pelagic marine ecosystems over the past 85 million years, with a focus on the tiny microfossils they leave behind in marine sediments.
